Abstract Background Interferon (IFN)- ?4, a type III IFN, production is controlled by dinucleotide frameshift variant (rs368234815-dG/TT) within the first exon of IFNL4 gene. Carriers -dG allele but not -TT are able to produce IFN-?4 protein. Patients with hepatitis C virus that do protein have higher rates viral clearance suggesting potential inhibitory role in liver-tropic infections. Methods...
CONTEXT There is growing evidence that interferon lambda 4 (IFNL4) polymorphism is related to sustained virological response (SVR) in hepatitis C virus (HCV) infection. We analyzed the relationship between IFNL4 (rs368234815) polymorphism and SVR in dual- and triple- therapy in HCV genotype 1, 2, 3 and 4 infected Asian, Caucasian and African patients. EVIDENCE ACQUISITION We performed a syste...
Genetic polymorphisms in the region of the interferon-λ genes (IFNL) associate with clearance of hepatitis C virus (HCV) infection. One of these polymorphisms, IFNL4 rs368234815, determines loss or gain of function of the IFNL4 gene by frameshift variation. The very same and a second one, IFNL3 rs4803217, are supposed to impact the expression of IFNL3: while IFNL4 rs368234815 is suggested to mo...
background: a dinucleotide variant rs368234815 in interferon lambda 4 (ifnl4) gene was recently found to be associated with the hepatitis c virus (hcv) treatment response. this study aimed to assess the impact of ifnl4 rs368234815 polymorphism on treatment response to pegylated?ifn alpha (peg?ifn??) and ribavirin (rbv) in hemophilic patients with chronic hepatitis c (chc). materials and methods...
BACKGROUND Cytomegalovirus (CMV) retinitis is a major cause of visual impairment and blindness among patients with uncontrolled HIV infections. Whereas polymorphisms in interferon-lambda 3 (IFNL3, previously named IL28B) strongly influence the clinical course of hepatitis C, few studies examined the role of such polymorphisms in infections due to viruses other than hepatitis C virus. OBJECTIV...
Interferon lambda 4 (IFN-λ4) is a novel type-III interferon that can be generated only in individuals carrying a ΔG frame-shift allele of an exonic genetic variant (rs368234815-ΔG/TT). The rs368234815-ΔG allele is strongly associated with decreased clearance of hepatitis C virus (HCV) infection. Here, we further explored the biological function of IFN-λ4 expressed in human hepatic cells-a hepat...
BACKGROUND Human genetic factors influence the outcome of pegylated interferon and ribavirin hepatitis C therapy. We explored the role of IL28B, APOH and ITPA SNPs on the outcomes of triple therapy including telaprevir or boceprevir in patients with compensated cirrhosis chronically infected with HCV-1. PATIENTS AND METHODS A total of 256 HCV-1 Caucasian treatment-experienced patients with co...
context there is growing evidence that interferon lambda 4 (ifnl4) polymorphism is related to sustained virological response (svr) in hepatitis c virus (hcv) infection. we analyzed the relationship between ifnl4 (rs368234815) polymorphism and svr in dual- and triple- therapy in hcv genotype 1, 2, 3 and 4 infected asian, caucasian and african patients. conclusions favorable ifnl4 rs368234815 gen...
BACKGROUND Polymorphisms in IFNL3 and IFNL4, the genes encoding interferon λ3 and interferon λ4, respectively, have been associated with reduced hepatitis C virus clearance. We explored the role of such polymorphisms on the incidence of cytomegalovirus (CMV) infection in solid-organ transplant recipients. METHODS White patients participating in the Swiss Transplant Cohort Study in 2008-2011 w...
AIM To analyze the genetic heterogeneity of the Amerindian and admixed population (Mestizos) based on the IL28B (rs12979860, rs8099917) and IFNL4 (rs368234815) haplotypes, and their association with spontaneous clearance (SC) and liver damage in patients with hepatitis C infection from West Mexico. METHODS A total of 711 subjects from West Mexico (181 Amerindians and 530 Mestizos) were studie...
